Document Model
The Document Model is a data modeling approach used in NoSQL databases, particularly document-oriented databases, where data is stored in flexible, semi-structured documents (e.g., JSON, BSON, or XML) rather than rigid tables. It allows for nested structures, dynamic schemas, and easy representation of hierarchical data, making it suitable for applications with evolving or complex data requirements. This model contrasts with relational models by emphasizing denormalization and scalability over strict ACID transactions.
Developers should learn and use the Document Model when building applications that require high flexibility, rapid iteration, or handling of unstructured or semi-structured data, such as content management systems, real-time analytics, or IoT platforms. It is particularly valuable in scenarios where data schemas evolve frequently, as it avoids costly migrations and supports agile development practices. Use cases include e-commerce product catalogs, user profiles, and logging systems where nested objects are common.
